An atom comprises an atomic nucleus with orbiting electrons. So the nucleus is smaller than an atom. To phrase it the opposite way, an atom is alwys larger than the nucleus (of the same atom of course!!)
A proton is smaller than a nucleus, which is smaller than an atom, which is again smaller than a molecule.
nucleus → chromosome → gene
The Nucleus
Chromosomes are made of DNA coiled around protein histones. So no, chromosomes are not smaller, but they are more condensed then when the DNA is unwound in strand form.

A chromosome is more "complex" than a gene.:)
nucleus → chromosome → gene
well, the chromosome is in the nucleus and there is a nucleus in the plant and animal
because the nucleus is not an atom; an atom is smaller than a cell
A chromosome is DNA in the nucleus of a cell.
No, chromosomes are smaller than cells. Chromosomes are found in the nucleus of cells which codes for the synthesis of proteins.

A cell nucleus would be smaller than a cell because a cell nucleus is inside the cell, so it has to fit inside.
